Multiscale Graph Construction Using Non-local Cluster Features

Reina Kaneko, Hayate Kojima, Kenta Yanagiya +3

This paper presents a multiscale graph construction method using both graph and signal features. Multiscale graph is a hierarchical representation of the graph, where a node at eac…

Time-Varying Graph Signal Estimation among Multiple Sub-Networks

Tsutahiro Fukuhara, Junya Hara, Hiroshi Higashi +1

This paper presents an estimation method for time-varying graph signals among multiple sub-networks. In many sensor networks, signals observed are associated with nodes (i.e., sens…

Efficient Learning of Balanced Signed Graphs via Iterative Linear Programming

Haruki Yokota, Hiroshi Higashi, Yuichi Tanaka +1

Signed graphs are equipped with both positive and negative edge weights, encoding pairwise correlations as well as anti-correlations in data. A balanced signed graph has no cycles…

Constructing an Interpretable Deep Denoiser by Unrolling Graph Laplacian Regularizer

Seyed Alireza Hosseini, Tam Thuc Do, Gene Cheung +1

An image denoiser can be used for a wide range of restoration problems via the Plug-and-Play (PnP) architecture. In this paper, we propose a general framework to build an interpret…

Optimizing in NN Graphs with Graph Learning Perspective

Asuka Tamaru, Junya Hara, Hiroshi Higashi +2

In this paper, we propose a method, based on graph signal processing, to optimize the choice of in -nearest neighbor graphs (NNGs). NN is one of the most popular appro…
